Question 24
|
For the daisy chain scheme of connecting I/O devices, which of the following statements is true?
|
It gives non-uniform priority to various devices.
|
|
|
It gives uniform priority to all devices
|
|
|
It is only useful for connecting slow devices to a processor device.
|
|
|
It requires a separate interrupt pin on the processor for each device.
|
Question 24 Explanation:
Daisy chaining technique tells the processor in which order the interrupt should be handle by providing priority devices.
→ In this all devices connected serially.
→ High priority devices placed first, followed by low priority devices.
→ In this all devices connected serially.
→ High priority devices placed first, followed by low priority devices.
